For years sex offenders have had to register with the county sheriffs office, which is then sent to Idaho State Police who runs the Idaho registry.
Offender Watch is a system that's been used in Ada, and Canyon counties since 2010. Now it's required in every county in the state. Which makes it easier for people to find sex offenders living around their home.
Other states also use the system which makes it easier to track offenders who are moving to the state.
The system also pays for itself because the state charges offenders an extra $40 a year in order to register with the state.
